Question

Python Language:

Please see program listed below of a game called: Rock, Paper, Scissors. Please add an exception, for example if the user inputs something else other than rock, paper or scissors, the exception will print message: "Enter only rock, paper, or scissors".

Also add option to keep playing the game, for example: print: "Would you like to play again? Enter Y or N". If the user says Y, the game will repeat, if N, the game will end and print "Good Bye!"

Current program:

import random
choices = ['rock', 'paper', 'scissors']
player = input("Choose rock, paper, or scissors: ").lower()
computer = choices[random.randint(0, 2)]
print("You chose: " + player)
print("The computer chose: " + computer)
if player == computer:
print("It's a draw!")
elif (player == "rock" and computer == "scissors") or (player == "paper" and computer == "rock") or \
(player == "scissors" and computer == "paper"):
print("The player wins!")
else:
print("The computer wins!")

Answer 1

input code:

output:

code:

import random
'''do untill user wants'''
while True:
choices = ['rock', 'paper', 'scissors']
'''make try catch for do exception'''
try:
'''take input from player'''
player = input("Choose rock, paper, or scissors: ").lower()
  
'''check input is valid or not'''

if(player=='rock' or player=='paper' or player=='scissors'):
  
'''generate random computer input'''
computer = choices[random.randint(0, 2)]
print("You chose: " + player)
print("The computer chose: " + computer)
  
'''check for win draw loss'''
if player == computer:
print("It's a draw!")
elif (player == "rock" and computer == "scissors") or (player == "paper" and computer == "rock") or \
(player == "scissors" and computer == "paper"):
print("The player wins!")
else:
print("The computer wins!")
else:
'''else generate error'''
raise TypeError()
except:
'''print the error'''
print("Enter only rock, paper, or scissors")
finally:
'''ask user for run again or not'''
while True:   
print('Would you like to play again? Enter Y or N:',end = '')
ch=input()
if((ch=='n')|(ch=='Y')|(ch=='y')|(ch=='N')):
break
else:
print('---Enter valid input---')
'''we do until user enter n or N'''
if((ch=='n')|(ch=='N')):
break
print("Good Bye!")
